There are always specific steps that ensure a targeted result in any process; they make use of three essential prerequisites—background information, resource availability and a predetermined goal. This principle does not go unnoticed when considering cloud migration solution. Though, to achieve the optimum results out of this process, while in line with this principle, the migrators must employ systematic steps that stand to endure the whole process. Some of those critical steps have been explored below.
1. Testing and Re-testing
It is always necessary to run planned tests to achieve a better hold of the current situation. The first stepping stone to a successful migration is successful testing. A migration test performs steps to ensure the data migration is ready or identifies the areas in which improvements are needed so that the process runs seamlessly. No firm can afford the loss of data – primarily when it belongs to a third party. Therefore, it becomes essential to work on the safe side. A migration test helps determine that a business workload will run in the cloud successfully after migration. The process involves multiple sub-steps such as:
• Replicating business data to the cloud
• Ensuring the testing solution creates a real-time copy of the replicated data
• Attaching replicated data to the testing workload on the compute instance before bringing it into production
• Repeating the tests seamlessly without manual effort or downtime to the business
These sub-steps are essential for successful testing because the dynamic IT environment can be severely impacted by configurational divergence. These crucial, automated and non-intrusive tests repeatedly run parallel to the business operations without affecting foreground data in any way.
2. Ensuring Continued Visibility into Business IT Health
Monitoring business IT health is vital in guaranteeing compliance with internal and external regulations, in addition to ensuring business critical service level objectives. The spectrum of business workloads falls so sporadically in public clouds that the real-time visibility and analysis of business IT health becomes very complicated.
Organizational cloud adoption is becoming common nowadays but very minimally in public domains. Many companies rely on the legacy and critical workloads hosted on premises. Since business applications have spread across multiple geographic locations and one or more clouds, this geographical and functional fragmentation can potentially affect IT operations. The various teams managing these workloads also contribute to the lack of visibility into IT health, which in turn increases expenditure costs. Thus, it is very wise to keep a proper eye on business IT health.
3. Adding a Resiliency Safeguard
When a third party’s data is taken into custody, it naturally becomes the responsibility of the service provider to ensure its protection. The data cannot be said to be “safe” until, and unless, it is protected by a resiliency safeguard. Loss of potential data may likely impact the business’ financial and reputational aspects. It is mandatory to remain vigilant and prepared for an outage that is beyond any control; this can be achieved by implementing a resiliency solution for public cloud workloads other than the basic resiliency add-ons made available by the cloud provider. A robust solution, on the other hand, helps instantaneously alert a business when an outage occurs, and shifting of workloads to another zone or region in the cloud is quickly performed.
4. Being Prepared to Migrate out of the Cloud Whenever Needed
The custody of business workloads can often be tricky, especially when one opts to move out of the cloud. According to IDC’s 2016 Cloud Computing survey, Vendor lock-in is one of the prime concerns of organizations surveying the public cloud. Other pressing matters include the sourcing and storing of data, and the security of cloud computing solutions; this indicates how the custody of company data plays a vital role in strengthening the business’ backbone. Cloud platform vendors prefer to have a firm grip on the business’ data which, at times, has made foreign clients skeptical. For this reason, most public cloud vendors offer their own free native tools to migrate solutions to their cloud. However, with the organizational objective shifting, the goals often tend to diverge from their first states after a decade; this often results in the need to move out of the cloud platform. Therefore, the business must be ready to act upon the need of the hour. Companies need to be prepared to migrate out, if the need arises, which should not cause any disturbance to the organizational pace.
